So from the options:
• Copper ❌ (not extracted by electrolysis of molten chloride)
• Aluminium ❌ (electrolysed from Al₂O₃, not chloride)
• Zinc ❌ (extracted by reduction with carbon)
• Sodium ✔ (obtained by electrolysis of molten NaCl in the Downs cell). so Sodium is the answer cuz it’s obtained by electrolysis of its molten chloride and it’s also above lead in the electrochemical series
